ABSTRACT
Imitation is closely allied to group-behavior; for it occurs usually, though not exclusively, among the members of a social group. The question of instinctive imitation has led to endless controversy. The problem may be stated in the following way. 1 Assuming instinctive behavior, in which a definitely patterned situation calls forth an equally definite response, can the same response be obtained from merely witnessing this behavior on the part of another? For instance, can instinctive rage be aroused not only by a menacing situation but also by witnessing the rage of another when oneself is not menaced?
